Munchclops eats and eats, but it is never satisfied. Scientists believe there is something akin to a black hole in its stomach, for Munchclops never creates any kind of biological byproduct. Oddly, it doesn't appear to actually need to eat to survive.
It is thought that its body is hollow with only a spectral ball of fire burning inside. It wolfs down its weight in food once a day, swallowing food whole with almost no chewing.
